Which electrons have a higher electron affinity?

Nonmetals have a greater electron affinity than metals because of their atomic structures: first, nonmetals have more valence electrons than metals do, thus it is easier for the nonmetals to gain electrons to fulfill a stable octet and secondly, the valence electron shell is closer to the nucleus, thus it is harder to …

Does fluorine have a higher electron affinity than carbon?

Fluorine’s electron affinity is smaller than chlorine’s because of the higher electron – electron repulsions in the smaller 2p orbital compared to the larger 3p orbital of chlorine….Electron Affinity Trends.

Does fluorine have a higher electron affinity than hydrogen?

The idea that fluorine’s electrons are at lower energy may be confusing. All the electrons in fluorine are at lower energy than the electron in hydrogen because fluorine has a much higher nuclear charge, with relatively little shielding from its own 1s electrons.

What is fluorine electron affinity?

Electron Affinity of Fluorine is 328 kJ/mol.

Why does fluorine not have highest electron affinity?

Fluorine, though higher than chlorine in the periodic table, has a very small atomic size. This makes the fluoride anion so formed unstable (highly reactive) due to a very high charge/mass ratio. As a result, fluorine has less electron affinity .

Which is larger hydrogen or fluorine?

Fluorine is bigger, but there are 9 protons in the nucleus, compared to 1 in case of hydrogen. So, the outermost electron in fluorine experiences more attraction than what hydrogen’s single electron experiences, in spite of larger size of fluorine.

Which has higher electron affinity chlorine or fluorine?

Electron affinity of fluorine is less than that of chlorine. Since, energy released during the formation of Cl− (g) ion is more than that released in case of F−(g) ion, the electron affinity of chlorine is more than that of fluorine.

Which has a larger atomic radius fluorine or neon?

As we know, neon has low van der waals force, and in neon the electrons are more concentrated, and therefore the attraction force from the nucleus decreases, resulting in greater neon size than fluorine. And the fluorine atomic radius is 160 pm, and the fluorine is 72 pm.

Which of the following has highest electron affinity fluorine chlorine?

We know that electron affinity decreases on moving down the group, but chlorine would have more affinity than fluorine because the size of fluorine is smaller than the size of chlorine. The bigger size of chlorine atom makes it accumulate more electrons and so, its electron affinity is higher.

Why does fluorine have a higher ionization energy than chlorine?

Since the most loosely held electron in fluorine is closer to the nucleus than chlorine, it takes more energy to remove the electron from fluorine than in chlorine. As a result, their energies are equal in magnitude but opposite in sign.

What is the relationship between electron affinity and electronegativity?

Electron affinity is related to electronegativity of elements. Simply speaking, the greater the affinity of electrons, the more eagerly the atoms of a given element join electrons to form ions (anions). The electronic affinity is most often given in electron volts (eV) or in kilojoules per mole (kJ / mol). Theoretically,…

Why does fluorine have a higher electron affinity than oxygen?

This also explains why fluorine has a larger electron affinity than oxygen, as the electron brought in from the environment is being added to the 2pz orbital of fluorine which is closer to the nucleus (than the outer orbital of an oxygen atom) at a lower energy level where it becomes the outermost electron of the F- anion.

What is the electron affinity of magnesium kJ mol?

Electron Affinity of Magnesium. Electron affinity of Magnesium is — kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.

What is electelectronic affinity?

Electronic affinity is a property specific to a given element. However, it may be slightly different for individual isotopes. When two atoms form a chemical compound, the electron cloud is shifted towards the element with a higher electron affinity.
